Chemistry

• Chemical Reaction Outcomes:


  • Neutralisation
  • Acid + Metal
  • Acid + Carbonate
  • Decomposition
• Neutralisation


  Acid + Base -> Water + Salt
• Acid + Metal -> Salt + Hydrogen
• Acid + Carbonate -> Salt + Carbon Dioxide + Water
• Percentage error (%) = |Expected Value - Experimental Value| / Expected Value
• $n =$$m/MM$


  Number of Moles = Mass / Molar Mass
• $c =$$n / V$


  Concentration = moles / Volume (L)
• Ionic Naming Conventions


  Metal + Non-Metal = Ide

  Metal + Polyatomic Ion = Ate
• Avagadro's Number


  6.022 x 1023 mol-1
• Guess Method


  Gather data, Units (make sure all correct), equation, sub-in, solve
